DETROIT — The founder of Domino’s Pizza is suing the federal government over ObamaCare’s mandatory contraception coverage.

Tom Monaghan, a Roman Catholic, says contraception is not health care but a “gravely immoral” practice.

His suit, filed Friday in federal court, also lists as a plaintiff Domino’s Farms, a Michigan office-park complex owned by Monaghan.

The lawsuit says he offers his employees health insurance that excludes contraception and abortion coverage. Under the new law, employers lacking such coverage run the risk of being fined.

The suit insists the law violates Monaghan’s rights and asks that a judge strike down the mandate.

Similar lawsuits are pending nationwide.
